Stars, bearingfi ha iigelmll races 7, inemher 6 bemg POSltiOIlBd tween the top of journal a citizen of the United States, and resident of Washington, in the District of Columbia, have new and useful Bh'llthe. following ,is a

invented a aring, of which cation.

The main objects of my invention are to provide novel means for holding balls with,- out the use of ri to provide novel means for their insertion in and removal the device to provide a novel load-bearing meinber esigned to ualiae the 1 an carry excessive end thi'u rand to provide an outer bearing member that can be easily and readily removed and replaced by a new one, to permit of rindthe ball races in said bearing me liliglf.

V t is also an especial object to provide novel means for freeing the bearing of all foreign substance or roken parts which otherwise would cause injury to the hearing which inightresult in serious accidents should it a pen while a train of cars were being mov at high speed.

It is further an object of my invention to provide a novel ball bearing device arranged to carry the balls into the oil contained, in the lower portion of the journal box rendering it unnecessary to use an absorbent substance for the purpose of conductingoil up to the. journal.

It is also, an, object to reduce the size of the spindle or axle end and to position same within the camel so that the ball members ari reach the 01 level as the outer circumference of the balls assbelow the axle opening in end of journa box.

- and carrying e on sigh fie armrd alleviconvenient position for ing is designed I a removal from the ournal without having to outer bearing 6 has b: .1 races 7 arranged as shown, the ball races or grooves 5 in memher 4 being spaced a little farther apart than the corresponding grooves or ball races 7 in member 6. The ob ect of this positioning of the ball races relative to each other is to cause the balls to automatically find their seat to balance the load and to carry end thrust. By using his articular design of outer bearin 6 it is possible to have deep grooves or ba 1 races, allowing opposed shoulders of the respective ball races 7 and 5 to extend farther around the balls for the pur ose of I providing additional bearing sur ace and end thrust capacity. In other words, the balls are diagonally engaged by the shoulders of the respective ball races of the outer and inner bearings. My construction permits tilting of member 6. The design of outer bearingfi disclosed also makes it possible to space the balls closely together in the bearing, giving a greater number of balls in a iven amount of space. Member 6 also is esigned to fit in the same space now occupied by the top plate of the present type of friction bearing now in common use, the main object of this being to save the expense of having to hange or especially design a journal box for this bearing. Further, I have provided means for removing and replacing damaged balls in the least possible time. This is accom lished by my novel ball container 8 whic is ma e 0 spring steel and provided with inwardly curved sta gel-ed flanges 9 which can be sprung 'su ciently to allow a ball to be pressed into position in the container 8 or removed from the container. This may be done without lifting the weight of the car from the journal at any time when the ball is not ,under the'upper bearing 6, and those under member 6 maybe shifted by merely rolling the car in either direction on the track, un'til the ball desired to be removed or replaced. rolls from under member 6 to a removal. This bearthroughout to permit of its remove the journa lnbox 1. Further, I reduce the diameter 0' "journal 3 as compared with thpsgg'itgyt in se, as the'strength of the greater. than that necessary to th ejga prior the purpose of gettm su surface by the old metho of firictidnfbearingxs, andlirlsobecause the typeno'w in' use as to, be of additional strength on account ,the fact that the bearin occasionally liecome heated to that extent that it wonld .giieatly reduce the a n capac ty of the journal. Such additi cna strength, is'unnecessarv lfaith a ball not nearly so apt to'become 'tion. The mainjobject of 1;

bearing because o,.. ,u1e fact th t they are ated by fricreduction of the'site of the journal is for e purpose of using or bringing back into use discarded car axles that have been removed from use because of the fact that the journal bearing had become worn to the extent that it could no longer be used with the friction ty e of bearing. Axles equipped with my ball ring will not be similarly subject to removal because of the fact that thereis no appreciable wear on the journal, the wear all being taken care of by the balls and their respective races.

It iswithin the contemplation of my in vention to apply my ball bearings to machinery other than railroad cars.

What I claim is:

1. In a device of the class described, the combination of an inner bearing member having ball grooves, an outer grooved bearing member positioned to engage over the portion of the journal subject to load press ire, a ball container consisting of a ring having inwardly curved flanges arranged in staggered relation to engage around an outer portion of the balls, spaced balls retained in position by the container during the time that the balls are out of engagement with the outer bearing member, as and for the purposes described.

2. In a device of the class described, the combination of an inner bearing member having a plurality of ball grooves, an outer bearing member extending only over the upper portion of the inner bearing member and having a plurality of corresponding grooves in the inner bearing member to permit of a tilting movement of the upper bearing member without interfering with the operation of the ball bearing, a ball colituiner ring engaging over the outer portions of balls to hold same in position when out of engagement with the outer bearing member, and a plurality of balls mounted in spaced relation in the container.

3. In a device of the class described, the combination of a journal box, a journal grooved bearing members mounted in spaced relation on thejournal, an upper grooved bearing member mounted over and in spaced relation to the first mentioned grooved bearing members, a ring-shaped ball container having inwardly curved ends engaging over. the outer portions of the respective balls to retain same in position when out of engagement with the upper bearing member the balls being positioned at their lowest station in the container to dip in oil carried in i races .the bearing members being mounted in spaced relation to each other, a journal,

a load-supporting bearing member eljtending over only the upper portion of the hearing rings, a ball container consisting (T a ring havingstaggered openings therein to receive the balls and having inwardly curved flanges to engage the outer portions of the balls to retain same in operative osition and to permit of the dropping 0 any broken balls to the bottom of the journal box, and a flurality ofballs for each ball race engage by the container, substantially as and for the purposes described.

5. In a device of the class described, the combination of an inner bearing member having ball grooves, an outer grooved hearing member positioned to engage and extending only over the portion 0 the journal subject to load pressure, a ball container consisting of a ring having ball engaging flanges supporting the balls in engagement with the inner bearing member the flan being disposed in staggered relation, be ls in the container, and means retaining the outer bearing member against longitudinal movement, substantially as shown.
